I was watching Soredemo Machi wa Mawatteiru when I noticed the shirt Arashiyama Hotori was wearing. I thought that the producers were commenting on the fact that Hotori is underage and is, therefore, off-limits to much of the older viewing audience.
Upon closer inspection, I noticed another detail – a small pill in the lower-left corner of her shirt. I postulate that it is hinting at her possible involvement in illegal drugs as a user and/or pusher.
Looking back at the previous epiosdes and careful observation of her erratic behavior seem to support this line of thinking. Of course, more data is needed, and I will keep my eyes peeled – all 21 of them.
